After tendering unconditional apology to former Akali Dal minister Bikram Majithia, Delhi Chief Minister Arvind Kejriwal has tendered apologies to BJP leader Nitin Gadkari and Congress leader Kapil Sibal's son Amit Sibal leading to judicial burial of two defamation cases against him. In two separate letters, filed along with joint applications for the closure of defamation complaints, Kejriwal has "regretted" his remarks. Kejriwal had levelled serious allegations against Gadkari and Amit Sibal during an anti-graft campaign.
